Hello to the group. I have a 2010 Edge SEL with All Wheel drive. Last winter, there were times that I questioned whether all wheels were being powered- due to poor handling and performance in relatively small amounts of snow and ice. With summer time driving, of course- I do not notice this feeling any more. Question- is there a simple way to determine if power is going to the rear wheels? Can I lift the front and rear of the car off the ground and manually turn each wheel to determine if the other wheels are turning? What should I expect to find if everything is working? Thanks in advance for any thoughts.
